Hello,
I work with libraries with lots of templates and, to reduce compilation
time, I split long definitions in separate files, and I do explicit
template instantiations in an extra compilation unit.
This used to work fine until (and including) gcc 3.4, but broke in gcc
4. You can find a small example code at:
http://www.enricozini.org/store/testcase.tar.gz
In that example, if I remove the #pragmas, it works. With the pragmas,
it complains about the default constructor, destructor, copy constructor
and copy operation are used but not defined.
I didn't find this behaviour documented in the gcc changes files, and
I can't understand if it's a problem in my code or a problem in gcc.
I'm this writing for help.
Please keep me Cc-ed as I'm not subscribed to the list.
Ciao,
Enrico
